Manufacturing Protocol

Precision Production Workflow

From technical CAD validation to cleanroom quality inspection, our engineering workflow ensures strict repeatability.

PHASE 01

Engineering DFM & Blueprints

Our engineers inspect your 3D CAD files or reference samples to calculate shrinkage compensations, wall thicknesses, and tooling paths. Comprehensive 2D manufacturing blueprints are delivered for sign-off.

PHASE 02

Master Prototyping & Mold Tooling

High-resolution SLA 3D wax printing is combined with vacuum investment casting or 5-axis CNC machining. First-article samples undergo dimensional verification, tactile fitment, and finish audits.

PHASE 03

Multi-Axis Machining, Casting & Polishing

Batch manufacturing utilizes multi-spindle Japanese CNC equipment, robotic surface buffing, and master hand-applied satin graining. Pieces undergo strict optical inspection before plating.

PHASE 04

Class 10,000 PVD Plating & Cleanroom QC

All ionized PVD deposition and final packaging takes place in ISO Class 10,000 cleanrooms to eliminate airborne dust. Every completed piece passes 72-hour artificial sweat immersion and AQL 1.0 optical checks.

Procurement Guidance

Frequently Asked Questions

Common technical and commercial questions regarding custom jewelry manufacturing and private label supply.

How do you ensure necklace chains do not break at the clasp?

All chain terminal ends are secured using reinforced jump rings that are fully laser-welded closed rather than mechanically crimped, ensuring exceptional tensile pull resistance.

Can you manufacture necklaces with custom branded logo tags?

Yes. We produce custom-shaped stainless steel hang tags with laser-etched or stamped brand logos affixed near the clasp closure.

What plating colors are available for stainless steel necklaces?

We provide 18K yellow gold, 14K pale gold, rose gold, deep black DLC, graphite gunmetal, and natural steel mirror finishes.

What is the typical Minimum Order Quantity for necklaces?

Standard initial runs start at 100 to 300 pieces per design, with the option to divide quantities across lengths or plating colorways.
